- "One of the main geographic features in 忘却溪谷 is a huge crevasse we call the 大裂谷. And believe you me, if you fall into that thing, you are NOT coming out."

The 大裂谷 is an area in 异度神剑X. It is located in western 忘却溪谷. This vast chasm effectively has no bottom, and falling into it has the same effect as death, and Dolls that fall in will also be destroyed. This effect does not occur when flying; Doll will be stopped at an exact distance into the chasm, making it much safer to explore as long as the 飞行模块 is always in operation.
A small floating island in the centre of the 大裂谷 houses 第304区FN点, a cave in the southeast contains the 恶魔的口袋, a smaller cavity in the chasm wall contains an 原生生物的巢, and the 珍稀种 「恐角」戈特哈德 and 「大祸」哈特穆特 are present above the chasm floor at all times.
The bottom of the chasm cannot be seen from above, and appears shrouded in thicker layers of air just below the bottom-most areas a flying Doll can reach. The walls of the chasm are dominated not only by rock, but by the same mysterious gigantic metal water pipes that appear interwoven into the rest of Oblivia's landscape.

Trivia
- From a geological viewpoint, the existence of a vast dry desert chasm within a continent is not wholly unrealistic. The 大裂谷 is reminiscent of the Messinian salinity crisis which happened repeatedly to the Mediterranean Sea during the Miocene era approximately 5-6 million years ago. These events included the tectonic closure of the Strait of Gibraltar, and the already hot and arid regional climate gradually causing almost the entire basin's seawater to evaporate, lowering the water level by thousands of meters and leaving a thick layer of rock salt evaporites on the bottom. These low dry abyssal plains were much hotter and the air much thicker, and the environment is believed to have been inhospitable to any non-microbial forms of Earth life. The salinity crisis came to an end when the Strait of Gibraltar tectonically reopened, allowing the waters of the Atlantic Ocean to flood back into the basin in an event known as the Zanclean flood. However, the geological nature of Oblivia's 大裂谷 is left unexplained, as is most of the rest of Mira's geology.
